芬顿技术降解新污染物毒性氧化副产物的控制措施
- Title:
- Control Measures of Toxic Oxidation By-product Formation during the Degradation of Emerging Contaminants by Fenton Processes
- 摘要:
- 芬顿（Fenton）技术在降解废水中新污染物（ECs）方面得到了广泛的研究和关注。然而，毒性氧化副产物的形成一定程度上阻碍了芬顿高级氧化技术的安全应用。本文系统探讨了芬顿及其衍生的类芬顿高级氧化技术（F-AOPs）应用于ECs降解的反应特点，ECs降解中产生的毒性氧化副产物的类型、风险、影响因素和形成机制，以及毒性氧化副产物的控制策略。建议未来结合人工智能以及密度泛函理论（DFT）计算等新方法全面预测产物毒性，并探究毒性氧化副产物形成的机制；同时，采用新技术实现高效、低毒催化剂体系的设计和应用，推动F-AOPs在水处理中的安全、绿色应用。
- Abstract:
- Fenton processes have attracted considerable research interest and attention for the degradation of emerging contaminants (ECs) in wastewater. However, the formation of toxic oxidation by- products has hindered the safe application of Fenton-based advanced oxidation processes. This review systematically discusses the reaction characteristics of Fenton and its derived Fenton-like advanced oxidation processes (F-AOPs) applied to ECs degradation; the types, risks, influencing factors, and formation mechanisms of toxic oxidation by-products generated during ECs degradation; and the control strategies for such by-products. This review suggests that future efforts should integrate new approaches, such as artificial intelligence and DFT calculations, to comprehensively predict product toxicity and investigate the mechanisms of toxic by-product formation. At the same time, new technologies should be employed to design and apply efficient, low-toxicity catalyst systems, thereby promoting the safe and green application of F-AOPs in water treatment.
